In angiosperms double fertilization produces a seed consisting of two major parts, the embryo and the endosperm.However, the molecular mechanisms underlying rice embryo development and coordination of embryo and endosperm growth remain poorly understood.

Both growth and tissue patterning are processes that occur continuously during plant life.A key question is how these are coordinated in space and time to generate plant shape and function.Hormones, n
Cytoplasmic male sterile (CMS) rice Zhenshan 97A (ZS97A) has been widely used in hybrid rice seed production in China.However, ZS97A suffers from serious panicle enclosure, which blocks normal pollina
Cytokinins play a crucial role in the maintenance of stem cell activity in plants and in various aspects of growth and development.Spatiotemporal distribution of bioactive cytokinins is finely control
A classical role of the hormone auxin is in the formation of flowers at the periphery of the reproductive shoot apex.In Arabidopsis, mutants in regulators of polar auxin transport or in the auxin resp
Observations gained from model organisms are essential for understanding life, yet it remains unclear to which degree they are applicable to distant relatives.For example, in the dicotyledon Arabidops
Cytokinin and nitric oxide (NO) have been characterized as signaling molecules to trigger cell division in tissue culture.Here, we show that the hypocotyl and root explants of Arabidopsis NO-deficient
A balance between the two phytohormones, auxin and cytokinin, is crucial to manipulate cell fate in an in vitro tissue culture.Arabidopsis ESR2 (Enhancer of Shoot Regeneration 2), a member of AP2/ERF
One of the central questions in developmental biology is that of pattern formation in organs.Leaves of most plant species have distinct dorsoventral (adaxial-abaxial) polarity, which is formed early d
The plant hormone auxin plays a critical role in regulating various aspects of plant growth and development, and the spatial accumulation of auxin within organs, which is primarily attributable to loc
Although callus formation is usually perceived to be a consequence of auxin-to-cytokinin gradients that are inadequate for the formation of shoots or roots, callogenesis may require additional conditi
